To improve dipstick diagnostic and environmental tests, just add tape

Simple paper-strip testing has the potential to tell us quickly what's in water, and other liquid samples from food, the environment and bodies -- but current tests don't handle solid samples well. Now researchers have developed a way to make these low...
